A Weighted HSI Multichannel Image Fusion

Aiming at the distortion problem for the existing fusion methods,we proposed the weighted HIS multichannel image fusion algorithm. Firstly,the source image was transformed from RGB color space to HSI;then,using different fusion rule to get the H,S and I components of the fused image; lastly,convert the fused image from HSI to RGB color space. The fused color image by using our method is much clearer than the existing methods. Besides,no color distortion was occurred,and the computation complexity was low. Experimental results show that the proposed algorithm works better than the other methods.
